I call that fitting a NPT to digital probe compression http://brewhardware.com/fittings/125-probecompression but in reality it's just a 1/4" tube compression fitting packed with some orings. Simple yet extremely effective. Everyone in my brew club has this setup on their plate chillers now.

Bobby confirmed that a Thermapen would also work in his setup which is what I'm going to use. Everything else will be just like the OP has. I'm still waiting for the Keg Cowboy chiller which has been on backorder for over a month.

Hey guys, I have decided to just use standard garden hose connectors on my 40-plate chiller. Who has those for purchase? I see that Bobby_M has his chillers already setup that way but I did not see the connectors on his site. I think Keg Cowboy has them...but are they in stock.

I have purchased 1/2" to garden hose brass connectors at common big box retail hardware stores.
